Hal Finkel e2ff00e117 PPC: Add some missing V_SET0 patterns
We had patterns to match v4i32 immAllZerosV -> V_SET0, but not patterns for
v8i16 (which occurs in the test case) or v16i8. The same was true for
V_SETALLONES (so I added the associated patterns for those as well).

Another bug found by llvm-stress.
